ABSTRACT: This study investigated the nature of relationships of demographic factors (age and job tenure) and job satisfaction facets with organizational commitment. The study also sought to determine the impact of demographic factors and job satisfaction facets on organizational commitment. A sample consists of 128 employees from service industry selected randomly. Employees were given a Job Descriptive Index (JDI) questionnaire and the Organizational Commitment questionnaire (OCQ). Pearson’s product moment correlation coefficient and multiple regression analyses were used to analyze the data. The Results of the study show that the mean values of job satisfaction and organizational commitment are at moderate side. A moderate significant positive relationship was found among job satisfaction facets, demographic factors, and organizational commitment. Supervision, pay, overall job satisfaction, age, and job tenure were the significant predictors of organizational commitment.
